The weight capacity for the 81-149 replacement glass door roller is 110 lbs per roller. I included a new picture of the roller with this post so you can see closer detail of the wheel. This roller works well with the 80-105 and 80-106 sliding glass door tracks. Each sliding door track has one run and the longest one is the 80-105 which is 8' long.
